What happenedTwo new books—Just Do It: How One Couple Turned Off the TV and Turned on Their Sex Lives for 101 Days (No Excuses!) by Douglas Brown, and 365 Nights: A Memoir of Intimacy by Charla Muller and Betsy Thorpe—have critics and experts questioning the role sex plays in modern relationships. Each book tells what happened when married couples tried having sex, every day.

What the commentators said

Having “lots of sex everyday” sounds like a great idea, said Dr. Belisa Vranich in the Huffington Post, but “then reality sets in: it’s sex with the same person every single day. Ev-er-y single day.” It would start to “become a chore,” like “laundry, bathing,” or “food shopping.”

Well, at least it's something to do, said Joe Burris in the Baltimore Sun. And, with the "nation's economic doldrums," staying home and having sex is something couples can afford, unlike going out. Maybe that explains why Just Do It is an instant bestseller, and 365 Nights is also getting a lot of attention, too.

Many young couples would love to devote more time to canoodling, said Ritu Verma in The Times of India. But, especially in cities, they're “too busy running the rat race to devote time in the bedroom.” But this “can be hazardous for a relationship”—intimacy “is the key to a happy and stress-free relationship.”
